Method for Removing SOx from Gas with Compound Alcohol-Amine Solution

A method for removing SOx from a gas, which comprises:

• making a compound alcohol-amine solution by mixing ethylene glycol and/or polyethylene glycol with hydroxyl/carboxyl organic compound having basic group containing nitrogen, bringing the compound alcohol-amine solution into contact with the gas containing SOx to absorb the SOx in the gas, wherein x=2 and/or 3;
• the hydroxyl/carboxyl organic compound having basic group containing nitrogen is one or more of hydroxyl organic compound having basic group containing nitrogen, carboxylic acid organic compound having basic group containing nitrogen, and carboxylate organic compound having basic group containing nitrogen, wherein the hydroxyl organic compound having basic group containing nitrogen is alcohol amine compound;
• the carboxylic acid organic compound having basic group containing nitrogen is organic compound comprising both carboxylic acid group and amine group in a molecule;
• and the carboxylate organic compound having basic group containing nitrogen is carboxylate organic compound comprising both carboxylic acid group and amine group in a molecule.
